So I bought a car the other day that came with alot of extras. One of the extras was a set of disc brakes that are supposed to be off a 67. They are a complete set, although they look completely different then the set I took off my other 67 which had factory discs. These new disc brakes are 4 piston and look old enough, but the back side looks completely different where everything mounts up, as do the brake lines. Did the 67's come with 4 pistons? I was told by a friend that the s-codes had them? Anyone with knowledge? Thanks!
